ROLLER WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 618,826, dated February 7, 1899. Application filed June 10, 1897. Renewed June 18, 1898. Serial No. 683,871. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS E. BARR, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new anduseful Improvements in Roller Window-Screens, of which the following is a specification.

My invention relates to improvements in roller window-screens and the means of operating the same. It relates more particularly to roller window-screens adapted for use upon the windows of railway-cars.

The objects of this invention are, first, to provide a compact and simple structure for the purpose which is easily kept in repair and which is easily operated; second,'to provide a simple and convenient structure for supporting the roller and protecting it outside of the car-window, and, third, to provide a roller window-screen, adapted for use upon car-windows, so constructed that it could be operated only by the person having authority. Further objects will definitely appear in the detail description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification, pointed out in the claims, and illustrated in the accompanying drawings, in which Figure l is an outside elevation view of a car-window partially opened with one of my improvedwindow-screens in place, portions -of the casing therefor being broken away to show details of construction. Fig. 2 is an en-. larged detail sectional elevation taken on a line corresponding to line 2 2 of Fig. 1, showing the car-window in the closed position. Fig. 3 is an enlarged detail sectional view taken on a line corresponding to line 3 3 of Fig. 2, with portions of the casing broken away and the window shown in sections. Fig. 4 is an enlarged detail sectional elevation of the roller-casing, taken on line 4 4 of Fig. 5, showing the bracket for supporting the roll. Fig. 5 is a longitudinal section of the roll-casing, with the roll in place in full lines, taken on a line corresponding to line 5 5 of Fig. 4. Fig. 6 is an enlarged detail view of one of the engaginghooks, the connecting-rod D and adjacent parts being shown in section and the position of the key and its operation being clearly indicated by the dotted lines. Fig. 7 is an enlarged detail sectional View through a modification of the key for actuating the engaging hooks.

In the drawings all of the sectional views are taken looking in the direction of the little sloping variety, against which the bottom rail rests when the window is closed. Resting upon the sill outside of the bottom rail of the sash is a casing J, which is securely attached thereto by any suitable means. A plate or bar G is detachably secured to the front or inside of the case J by suitable screws or other means, so that the casing can only be opened from the inside. The usual brackets K, with bearings to retain the shaft on which the roller revolves, are secured to the windowframe P at each side.

The roller I revolves on the shaft 1, and tension is put upon the same by a suitable spiral spring. The window-screen. or wirecloth M is secured to the roller at one end by suitable means, so that the roll acts to wind it up when the window is lowered. Astrip of metal issecured to the upper end of the screen and is wrapped around a suitable rod H, which serves as a binding for the edge of the screen and affords means of attachment to the sash-rail above. Hooks D are pivoted on the brackets E to the sash-rail above and project down and engage the rod H from the outside when the sash-rail is lowered into position. A rod D connects the upper ends of the hooks together, so that they are operated like levers to release or engage the rod H at thetop of the screen.

A spring F is secured to the sash-rail and extends up and loops over the rod'D toward the middle and throws it outwardly, so that the hooks D D are thrown toward the sashrail at the bottom and normally engage the rod H of the binding.

The usual sash-lift A is provided for the window-sash, and through the same, which serves as an escutcheon, a keyhole is formed, through which the key N, having a sloping bit, is inserted, as clearly appears in Fig. 3, where it can be turned down and draw the rod D toward the sash-rail, thus operating the hooks D D, causing them to release the wire cloth or screen when it is desired to raise the window without raising the screen. Extending over the hooks D D and rod D is a casing C, which extends downwardly and outwardly and laps onto the outside of the easing J, to which it fits closely, thus preventing the entrance of any moisture or dirt into the screen when the window is closed.

The wire-cloth is provided with an enlarged edge which passes up and down inside the guideway L. The guideway can be formed of a single piece folded with a projecting flange, or it can be made of two independent pieces lapping at the flange, where they may be attached by screws or other suitable means.

It will be observed in this structure when it is desired to remove the roller that the key is inserted and the hooks withdrawn and the window raised, when the plate G can be removed and the roller be easily taken out, and it will also be observed that when the parts are in position for this it is impossible to tamper with the same from the outside of the car. As the key can be kept by the porter or other officials in the car who understand its operation, no difficulty will be experienced in properly controlling and operating the screen when it is desired to release the same, and the passenger or whoever else attempts to operate it will always bring the screen into place in the window.

The key can be divided, as I have indicated in Fig. 7, a portion of it, with the bit, remaining pivoted in the bottom rail of the sash, containing an irregular socket, and the remaining portion, bearing the bow, being provided with an irregular shank corresponding thereto for insertion into the socket to operate the same.

From these statements it must be clear that numerous variations are possible in the structure of my improved window-screen without departing from my invention. The spring for holding the rod in place might be otherwise constructed. The exact structure of the roll and method of attaching the netting are immaterial to this invention. The number of hooks D is not material, as they can be in creased or diminished to correspond with the width of the window on which the device is used, and the exact form of the binding at the top of the wire-cloth could no doubt be varied without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a car-window screen, the combination with the window frame and sill; the bottom rail A; hooks, D D, pivoted to suitable brackets on said bottom rail; connecting-rod D, between the said hooks; a spring E on said rail for holding the rod outwardly; the key N for insertion through the sash-rail with a sloping bit to act upon the rod D, to operate the books; a casing G secured to the sash-rail A and projecting outwardly and over the hooking mechanism; an outer casing J secured to the sill and frame of the window; a removable plate G secured to the front there of; a spring-roller within the casing J; a suitable screen secured to said roller with a binding on its upper edge positioned to be engaged by the hooks D all coacting together substantially as described for the purpose specified.
